EGG-BEATER.

Specification of Letters Patent. Patented B131. 21, 1916.

Applicationfiled November 15, 1915. Serial No. 61,617.

To all u'hom z't-may concerit:

Be itknown that I, IRAE. STUMP, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Egg-Beaters, of which the following is a specification.

My invention relates to improvements in egg heaters, and more particularly to that. class or type in whlch stationary and rotary loops are employed, one of the loops being adapted to revolve within and in close proximity to the path of the other.

The primary object of the invention is to provide a generally improved sanitary device of this class which will be exceedingly simple in construction, cheap of manufacture, and efficient in use.

A further object is the provision of an improved egg beater which may be readily operated by one hand through the medium of the improved spiral actuating plunger or handle suitably arranged and connected to improved spiral actuating mechanismadapted to intermittently engage and actuatethe rotatably mounted loop through the" medium 1 of a suitable cooperating clutch or ratchet head, all the working parts be1ngsu1tablyinclosed within the stationary handle thereby providing an exceedingly sanitary device of this class whlch may be easily washed and cleansed.

nism, together with improved means of v mounting and assembling the same.

Vith the above mentioned and other ends.

" in view, the invention consists in' the novel construction, arrangement, and combination of parts, hereinafter described. illustrated in' some of its embodiments in the 'accom. panying drawings, and particularly pointed out in the appended claims. a Referring to the drawings, forming a par 'ofthis specification, Figure l, is a side elevation of an egg beater constructed in accordance with this "invention. a

spring resisted spiral actuating plunger andhandle being partially depressed and the longitudinally and circumferentially mov- "able spiral being in engagement with. the

Similar numerals of reference designate like parts throughout all the figures of the drawings. y

The improved egg beater comprises a stationary loop head 1, provided with a plunger guide or stationary handle member 2, the latter, in the present instance,'comprisingi a tubular barrel or casing 2, provided at its ends with guide or bearing heads-2 The guideor bearing heads 23in the present instance, a-re' provided with central bearing openings 2",. to receive and contain a guide shaft-3, the latter, in the present'instance, being rotatably mounted and secured as against longitudinal movement by means of bearing heads 3". i

The shaft 3, is provided with a rotary loop 4, adapted to rotate Within the path of the stationary loop head 1, said rotary loop, in thepresentinstanc'e, being secured upon the shaft 3, by having its members wound about, in opposite directions to form 'spiral convolutions 4t, and terminating at opposite sidesof the shaft informing oppositely arranged clutch lugs or projections P; .(s e Fig. 7 said spiral convolution-s l*,}anc projections or lugs a formingwhat may be termed a clutch or ratchet head to'receive and cooperate with thelongitudinally and circumferentially movable spiral to be now described.
